Seasonal Diversity and Distribution of Butterflies in G.Venkataswamy Naidu College Campus, Kovilpatti, Tuticorin District, Tamil Nadu

The genus Hersilia was established by Audouin in 1826 with H. caudata Audouin, 1826 as the type species. It is the most speciose hersiliid genus presently comprising 79 described species worldwide (World Spider Catalog 2017, version 18). There are seven species known from India: H. aadi Pravalikha, Srinivasulu & Srinivasulu, 2014, H. longivulva Sen et al., 2010, H. orvakalensis Javed et al., 2010, H. savignyi Lucas, 1836, H. striata Wang & Yin, 1985, H. sumatrana (Thorell, 1890), H. tibialis Baehr & Baehr, 1993. This paper is based on fresh material collected from the patches of scrub jungle enclosed within the Madras Christian College campus, Chennai, Tamil Nadu, India. Both sexes of H. savignyi are illustrated. H. aadi Pravalikha, Srinivasulu & Srinivasulu, 2014 is synonymized with H. savignyi Lucas, 1836.

Predatory Insects

Butterflies are the sensitive insects which react quickly to any kind of disturbances like changes in the habitat quality and environmental variation. Apart from pollinators they play a major key role in food chain, being prey for birds, reptiles, spiders and predatory insects. It is one of the most important assemblages of insects that act as biodiversity indicators as well as nature’s gardeners. The objective of the present survey is focussed on the assessment of the diversity and abundance of butterfly conservation priorities in the study area. A total of 33 species of butterflies under 5 families and 26 genera were recorded during from December 2017 to February 2017 in the Kalimahal College campus, Sembarnarkoil, Tharangambadi Taluk. Nymphalidae was recorded as the most dominant family in terms of number of species (13) and number of genera (9), followed by Pieridae 8 species (6 genera), Lycaenidae 6 species (5 genera), Hesperiidae 3 species (3 genera), and Papilionidae 3 species (2 genera). Species richness (25), Simpson diversity index (0.7206) and Shannon ‘H’ index (1.783) were high in the month of December 2017. Simultaneously the Dominance index (0.6634) and Species Evenness (0.2871) were high in the month of February 2018. The outcomes of the present study highlight the importance of institutional campuses as a preferred habitat for butterflies. If the landscaping and maintenance of gardens are cautiously planned, the diversity of butterflies may increase in college campus providing a rich ground for butterfly conservation as well as for research.

Unknown Male

A total of 108 species of spider species belonging to 84 genera and 25 families were identified from the scrub jungle of the Madras Christian College campus. Pagida salticiformis (O. Pickard-Cambridge, 1883) is recorded for the first time from India. Langona tigrina (Simon, 1885) is rediscovered 135 years since its first description and the unknown male is described and illustrated. A new combination, Langona davidi (Caleb, Mungkung & Mathai, 2015) comb. nov. is proposed for the species previously placed in Phlegra. Three new synonymys have been recognized: Clubiona foliata Keswani & Vankhede, 2014 and Clubiona pashabhaii Patel & Patel, 1973 are junior synonyms of Clubiona filicata O. Pickard-Cambridge, 1874 and Myrmarachne megachelae Kumar & Mohanasundaram, 1998 is a junior synonym of Myrmaplata plataleoides (O. Pickard-Cambridge, 1869). Distribution records of several species have been updated and as many as 31 species are recorded for the first time from Tamil Nadu State. The family Salticidae is the most diverse with 28 species belonging to 22 genera followed by Araneidae with 19 species in 11 genera. Guild structure analysis revealed seven feeding guilds of which, stalkers and orb-web weavers are the dominant feeding guilds followed by ground runners, ambushers, and scattered line weavers, respectively.
